Notes:
a
Plait point.
Method/Apparatus/Procedure:
The analysis method was used. 100 mL of ternary mixture, prepared by weight, was placed in thermostat, agitated many times and then leave for several hours to separate. The density and refraction index of each phase was measured. Inversion of density was observed.
Source and Purity of Materials:
(1) Source not specified; d(25°C,4°C)=0.7853.
(2) Source not specified; d(25°C,4°C)=0.8593, b.p.=138.1°C at 739 Torr.
(3) Source not specified.
Estimated Errors:
Solubility: Not reported.
Temperature: Temp. ±0.02°C.
